Abstract (en)

[origin: WO0147420A1] An apparatus for medical diagnosis and/or therapy is provided with an electromagnetic object sensor in order to prevent collisions between movable parts and, for example, a patient to be examined. The sensor may be provided with sensor electrodes (16 and 18) for capacitive detection of obstacles. In order to extend the area of sensitivity of the sensor electrodes in such a manner that it encloses the area in front of the X-ray entrance window (20) of the image intensifier (6), an additional electrode is provided in the beam path between the X-ray source (4) and the image intensifier, which additional electrode is coupled to sensor electrodes (18). The additional electrode includes a carrier which is provided with a thin metal layer, both being transparent to X-rays. The additional electrode may be subdivided into sectors (28-1, ..., 28-4) which correspond to sectors (18-1, ..., 18-4) of the sensor electrode in such a manner that the position of an obstacle relative to the image intensifier can be determined.
